Recent Met Office forecasts and observational data for London indicate a stable high-pressure system moderating late-summer temperatures, with ensemble models showing peak readings likely between 23–25°C under partly cloudy skies and light northerly flow. This positioning aligns with seasonal norms for late August, where average daily maxima hover near 22°C, though urban heat-island effects and minimal cloud cover could nudge the maximum slightly higher. Updated model runs from the past 24 hours have narrowed the range, reducing probabilities for extremes below 22°C or above 26°C, while traders weigh the final official reading against potential afternoon warming.

This market will resolve to the temperature range that contains the highest temperature recorded by NOAA at the London City Airport Station in degrees Celsius on 25 Aug '26.
The resolution source for this market will be information from NOAA, specifically the highest reading under the "Temp" column for all times on this day, available here: https://www.weather.gov/wrh/timeseries?site=eglc
To toggle between Fahrenheit and Celsius, click the "Switch to Metric Units" button until the relevant table displays °C.
This market can not resolve until the first data point for the following date has been published on the resolution source.
The resolution source for this market measures temperatures to whole degrees Celsius (eg, 9°C). Thus, this is the level of precision that will be used when resolving the market.
Revisions to temperatures recorded within this market's timeframe will be considered until the first datapoint for the following date has been published, after which any alterations will not be considered.Recent Met Office forecasts and observational data for London indicate a stable high-pressure system moderating late-summer temperatures, with ensemble models showing peak readings likely between 23–25°C under partly cloudy skies and light northerly flow.
